So, if there is a current thread on this topic, I couldn't find it. All of the threads that came up were old and the information has changed! So I thought Heathrow Express was running on Christmas Day. Apparently not... The old threads said it ran 365 days a year! Anyhow, can I take for granted that cabs will be around on that day? I know that will cost about $100 (our hotel is near King's Cross). Does anyone know of any money saving alternatives? Thanks!
